PRINTERS Quom.

SPECIFICATION forming part of Letters Patent No. 692,023, dated January28, 1902.

Application filed March 14, 1901.

To all whom, it may concern.-

Beit known that I,WILLIAM H. LYNOHARD, residing at No. 133 Bentonstreet, Council Bluffs, in the county of Pottawattamie and State ofIowa, have invented certain useful Improvements in Printers Quoins; andIdo hereby declare that the following is a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, which form a part of this specification.

This invention has relation to a new and novel improvement in printersquoins.

The object of my invention is to provide a printers quoin so constructedthat the members thereof, which are adjustably secured to one another,may be moved laterally without longitudinally displacing the same, andmy device further embodies certain other combinations of mechanicalinstrumentalities, as will be described more fully hereinafter.

In the accompanying drawings 1 have shown in Figure l a top view of theprinters quoin embodying my invention. Fig. 2 shows an elevation of oneof the counterpart members. Fig. 3 shows aview on line 00 as, Fig. 2.Fig. 4 shows a top View of one of the quoin members. Fig. 5 shows a sideelevation of the rack-wedge as used in my invention. Fig. 6 shows an endview of the rack-wedge. Fig. 7 shows a view of the pinion-headed leveras used in my invention, while Figs. 8 and 9 show, respectively, a sideand top View of the hook as used in connection with the lockingtool usedin my invention.

The aim of my invention is more particularly to provide a printers quoinso constructed that the same may be placed within a very narrow spaceand, further, having its sides in the form of parallel bars, so that thesidesticks or furniture employed with the ordinarily-constructed quoinsmay be eliminated. This construction enables the operator to look a formwithin narrow space and insures a mechanical square even lock'up to theimposed form.

In furthering the aim of my invention I provide two counterpart quoinmembers 2 2,

which are provided with the enlarged ends 9 Serial No. 51,113. (Nomodel.)

9. These quoin members 2 2 are in the form of narrow metal bars, as willbe understood in referring to Figs. 1 and 4. Adjacent the enlarged heads9 9 I provide a seating 3 in removing or cutting away a portion of themetal, so that the end 20 of a suitable hook 18 may work between thecounterpart seatings of the quoin members when theyare in their closedor united condition. In Fig. 1 I have shown one of my printers coins asextended, showing the same in its fullest lateral position. Thesecounterpart quoin members are provided with two or more wedge-faces 5and 8.

(Shown more clearly in Fig. 4.) Centrally extending from each wedge-faceis a rib, the wedge 5 being provided with an extending rib (i'and thewedge 8 with an extending rib 7. To one of these counterpart quoinmembers 2 are fixed the pins 4 4, to which pins are loosely secured theremaining quoin member, so that one quoin member loosely works upon thepins fixed to the remaining quoin member. The heads of these pins areflanged slightly to prevent the quoin member workin g ofi. Workingbetween these counterpart quoin members 2 2 is the rack-edged wedge 1,which is provided with a central groove 13, adapted to receivethe ribs 7and 6, while the wedges 14 14 are made complementary to the wedges 5 and8. This wedge for the sake of convenience is in duplex form, so that twodistinct but united wedges are used, the quoin members 2 also beingduplexed, in that they have two or more separate wedge-faces 5 and 8.

When the quoin members are distended to their fullest capacity, thewedge-faces 5, 8, and 14 are engaged to provide the mechan ical power,while the ribs 6 and 7 are employed to prevent the wedge 1 from workingOK the quoin members. It should be remem bered, however, that these ribs6 and 7, as well as the groove 13, could be eliminated without departingfrom the spirit of my invention. From this it will be seen that Iprovide two counterpart quoin members 2 2, which are adj ustably unitedbymeans of the pins 4, and between which quoin members loosely works therack-edged wedge 1.

Used in connection with my quoin is a pinion-headed lever 15, the head16 being cut in the form of a pinion adapted to mesh with Ice the rackedges 12 of the sliding wedge-bar, adjustably held between the quoin.Passing through the opening 17, Within the pinionhead 16, and an opening19, within the bifurcated end of the hook 18, is a suitable pin, so thatthis hook 18 is pivotally secured to the pinion-head 16. The hooked end20 is adapted to work-over and engage the pins 1.

In using my quoin in securing a form the operator would place the quoinin its closed condition, in which instance the rack-edged Wedge 1 wouldbe at one end between the united or closed quoin members. To distend thequoin members, the operator would pass. the hook 18 about one of thepins 4: and then insert the pinion-head 16 of the lever 15 within therack of the wedge 1. The lever 15 would then be tilted on its fulcrum,which would be formed by means of the pinion-head 16, and this revolvingof the stationary-held pinion-head would impart a movement to therack-edged wedge 1 to spread the counterpart quoin members. Should thelever 15 be carried down its full length, the pinion-head is removedfrom the rack l, a new hold is taken, and the wedge again led forwarduntil the proper tension has been obtained. In

their closed condition the hook would be inserted within the seatings 3to engage the pins 4. It should be remembered, however, that theseatings 3 could be eliminated, as the hook could be made to directlyengage the ends 9 of the counterpart quoin members.

These quoins are made in lengths to correspond to the lengths of theordinary laborsaving furniture.

Having thus described mysaid invention, what I claim as new, and desireto secure by United States Letters Patent, is

1. The combination with two loosely-connected counterpart quoin members,each member being provided with a plurality of wedge-faces, eachwedge-face being provided with an extending rib, of a wedgecomplementary to said wedge-faces and provided with racks upon oppositeedges, and a groove to receive said ribs, as and for the purpose setforth.

2. The combination with tWo counterpart quoin members, of terminal pinsuniting said quoin members, said quoin members being cut away to providea seating adjacent said pins, each quoin member being provided with aplurality of wedge-faces, a rack-edged wedge complementary to andsliding between said quoin members, apinion-headed operating-lever, anda hook secured to the pinionhead of said lever, and adapted to engagesaid terminal pins, while said head engages said rack-edged wedge, allarranged substantially as and for the purpose set forth.
